IMPROVEMENT IN WASHING AN-D WRINGING MACHINES COMBINED.

' Specication forming partof Letters Patent No. 122,441, dated January2, 1872.

` improvements the following is a specification,

reference being had to the accompanying drawing, which is a perspectiveview of my machine.

The invention relates to that class of combined washin g and wringingmachines in which three rollers are used, of which twothat is, the upperone and the lower one-are mounted in' movable bearings and are held inclose contact with a third intermediate roller, whose bearings are notmovable, and which is usually employed to drive the Vother two, itsshaft being provided with a crank througlf which power may be applied.rhe invention consists in a novel combination and arrangement of threerollers and their actuating' springs, as

` will be fully explained.

. In the drawing myinachine is represented' as applied to a suitabletub, the side of which is broken away in order to more fully show thedevices'. The frame consists of two end pieces, B, bottom girts B1, (oneupon each side,) and top girt 13 2. E is the central rol1er,its shafthaving a crank, E', upon one end, as shown. Its shaft is mounted invertical slots I), and is therefore free to rise and fall within certainlimits. lBy preference this roller is* made with a iiuted surface. A Aare tongue-springs secured to the upper side of girt B2. rlheir freeends project beyond the fend pieces B and are connected with the shaftof roller D by means of rods a, the upper ends of said rods beingthreaded and provided with thumb-nuts C, whereby the tension of springsA may be increased and roller D pressed against roller E with anydesired force. Dl is the wringing-roller. slots or in movable be'arings, and is held again st roller E by a bar-spring, D2, the pressurebeing regulated by a set-screw, d, working in a thread in. girt B2.

Although springs A A are practically two independent springs, yet forconvenience Iusually make them in one piece, as shown.

In practice I usually employ a supplemental roller, F, over .which thearticles pass as they go through between the wringing-roller D1 androller E, this arrangement servingto keep said articles from contactwith roller D, which is apt to be wet.

, I prefer to make roller E of rubber, as I nd that the clothesA aremore readily freed from dirt by the action of the iiuted roller Dagainst an elastic one than against an unyieldin g one.

It will, of course, be understood that the springs AA and D2 enablerollers D and D1 to yield so as to allow any desired thicknessof goodsto be passed through by the action of rolle-r E operated by the crank.

I do not claim, broadly, tire combination of the three rollers D D1 andE; nor do I claim, broadly, applying the pressure to the lower roller bymeans of the side rods a; but

The herein-described combined washin g and wringing machine, consistingof the rollers D D1 E, springs A A D2, rods ai, adjusting-screws C d,and crank E1, these parts being combined and arranged for jointoperation substantially as set forth. SOLON GONKLIN.
